Plain Haematocrit Capillary Tubes are essential for precise blood analysis. These tubes, manufactured without heparin, have an internal diameter ranging from 1.1 to 1.2mm, and an external diameter spanning from 1.5 to 1.6mm.
Forged from premium glass, these micro-haematocrit capillary tubes are robust and are a standardised length of 75mm. Each vial contains a total of 100 capillaries, while a single box accommodates 10 vials, ensuring a consistent supply to meet your requirements.
The tubes are supplied fire polished at the colour-coded end, which is coloured blue to denote non-heparisation.
These tubes are for gauging the volume percentage of red blood cells in blood samples.
